Air Conditioning Repair Question: My Geothermal System Won’t Cool

Geothermal systems use a series of pipes buried in the soil to transfer heat between the ground and your house. In the summertime, the system absorbs heat out from your building and discharges it in the soil. In the winter, the process is reversed, as the system absorbs heat from the ground in order to warm your home. In Fairfield, OH, air conditioning specialists like Bartel’s Heating & Cooling have geothermal system experts available to address problems when they arise. If your geothermal system won’t cool for some reason, it’s time to give them a call.

Problems with a geothermal system can stem from a number of sources. Closed-loop systems use a heat exchanger to transfer heat between the antifreeze that circulates underground and the refrigerant in the heat pump, which heat or cools the air that is circulated in your home. A leak of either component could affect the system’s ability to cool your house. A trained professional can recharge the refrigerant or add additional levels of antifreeze, as wells as identifying the source of the leak and sealing it up.

Open loop systems, on the other hand, often use water in the underground loops; if the water flow is disrupted or cut off by damaged components within the system itself, it will impact the system’s ability to generate cool air. Dirty coils and filters in the heat pump could interfere with cool air as well, disrupting the flow of air and possibly affecting the pressure elsewhere in the system. It may also be a problem with the thermostat itself, which usually needs to be set to cool the house in the summer and heat the house in the winter. If it hasn’t been set properly, it may not be circulating cool air like it should.

Regardless of the causes, a non-functioning geothermal system requires trained experts to properly diagnose and repair.
